Four seeds were sown on four different surfaces: On the path, rocky ground, sown among thorns and rich soil. The seeds are the word of God and some of the disciples represent the four environments.
Jesus’ wanted the disciples to be the rich soil at all times (to hear the word, understand it and live it). But God has also given them the freedom of choice to choose what surface they would be.
We also have that freedom of choice to choose where we would be among the four surfaces. However, as far as Jesus is concerned He always wants us to be the rich soil. You may ask for what reason? The answer here is very simple: God wants us to be at His bosom in heaven when our earthly journey is over.
